Castellani and Giuliano

Castellani and Giuliano

Lot 323, Spring 2017

Giuliano Brooch (Carlo and Arthur Giuliano), Diamond, Sapphire, and Chrysoprase, Lot 323, offered in the Spring 2017 Important Jewels Auction

The nineteenth Century is a time of change. Industry creates a growing middle class. Archaeology is invented, and all around the Mediterranean, sites reveal beautiful decorative items of the ancient world. Artifacts of ancient Greece, Egypt, and the Italian peninsula provide inspiration. Designers look fondly back on the ancient world. Castellani and Giuliano are two jewellers drawing on this inspiration, and become two of the most important names in jewellery history.

Castellani

Fortunato Pio Castellani was a collector and dealer in artifacts of the ancient world. Founding a business in Rome in 1814, Castellani is one of the first dealers to bring ancient decorative items of beauty to 19th century customers.

Lot 327 dupuis.ca Spring 2017

Castellani Caduceus Hairpin, Circa 1875, Lot 327 offered in the Spring 2017 Important Jewels Auction

Castellani’s believed the ancient world produced the most beautiful items. He also felt the forgotten styles and techniques of our ancestors should be resurrected. The delicacy of hand made and custom ornamented artifacts of the ancient world would benefit connoisseurs and collectors.

The house of Castellani, under Fortunato’s sons, Alessandro and Augusto, thrived in Rome. They began creating fine jewels inspired by jewels of the ancient world. The company gained a reputation for being the go-to place for interesting and beautiful interpretations of ancient design in a modern (nineteenth Century) world.

Symbols found in ancient art, mythological creatures, ancient wine jugs, (for example, a ram, and amphora, seen in the brooch, below), and religious images are among the forms commonly found in Castellani jewels. A caduceus, seen in the hairpin, above, was an ancient Greek and also ancient Egyptian symbol of messengers (bringers of good news), only more recently has the symbol come to represent the medical profession. The jewels often contain mixed images drawn from different places in ancient history.

Archaeology

Lot 326 www.dupuis.ca Spring 2017

Castellani brooch, Circa 1880s, a mythical ram’s head with an amphora, Lot 326, offered in the Spring 2017 Important Jewels Auction

The Castellani family often visited archaeological sites. They examined ancient jewels as they were excavated. With access to these jewels, the family became fascinated by metal-working techniques that had been lost in the mists of time.

Delicate filigree and texturing with tiny grains of gold (“granulation”) were decorative elements that the Castellani family really wanted to revive. After decades of work, they re-discovered these methods and produced incredible jewels. As a result, the elements of ancient design were incorporated into highly desirable jewels which appealed to Europe’s wealthiest classes.

Worldwide Reputation

By the late 1850s, travellers to Italy and Rome absolutely had to make a stop at Castellani’s to make a purchase of their famous “revival” jewels. These treasures were so popular that Castellani opened stores in Paris and London.

Giuliano

Lot 325, Spring 2017

Giuliano pendant on a Tiffany & Co chain, with Garnets, Circa 1890, Lot 325, offered in Spring 2017 Important Jewels Auction

The London office was opened by Castellani protege Carlo Giuliano. Giuliano became fascinated by the jewels of the Renaissance. Thus, he shifted his focus from ancient to Renaissance jewels of the 1500’s. The jewels of Giuliano rarely focused on expensive gemstones, the gems were seen as an integral part of the design. The pendant, above, is a perfect representation of this focus.

The jewels of the ancient world had very little enamel, but there was widespread use of enamel in the Renaissance. The Castellanis used stone inlay and mosaic in their ancient revival jewels. Giuliano, however, worked widely with delicate enamels.

Giuliano opened his own business in London, and immediately developed a reputation for extraordinary Renaissance revival jewels. A trademark of work by Giuliano was very delicate enamel work. Of great note is the unique combination of black detail on white enamel, or white on black. Below, the brooch shows the delicate enamel work of Giuliano.

Lot 322 Spring 2017

Giuliano Brooch (Carlo and Arthur Giuliano) garnets and enamel, Circa 1900, Lot 322, offered in the Spring 2017 Important Jewels Auction

Giuliano and Castellani jewels are known for being decorated on the back. Most jewellers don’t bother with making the back of jewels pretty. Both Castellani and Giuliano looked at the complete beauty of the entire jewel. The pleasure of a beautiful reverse side of a jewel provides joy to the wearer each time they put it on and take it off.

While Castellani and Giuliano made what are called Archaeological and Renaissance Revival jewels, they were inspired by, but not direct copies of designs and styles from bygone eras. Cameos, similar to the one below, are often seen in ancient Roman jewels, but this cameo is framed by classic Giuliano black and white enamel.

Lot 324, Spring 2017

Giuliano Cameo Pendant, Lot 324, offered in the Spring 2017 Important Jewels Auction

Castellani and Giuliano are two of the most important names in the history of jewellery. These two names generate real excitement among collectors. At Dupuis, we are very pleased to have the opportunity to offer six important jewels from these two houses in a single auction.

Diamond Carat Weight: Large is Rare

Diamonds By The Carat: Large Is Rare

Lot 400, Spring 2017

Van Cleef & Arpels ring, marquise 6.47 carat D colour, VS-1 clarity, Lot 400, offered in the Spring 2017 Important Jewels Auction, sold for $240,000


We weigh diamonds in carats. A carat is a metric measurement of 200 milligrams. That means 5 carats equals a gram. Most people will never own a gram of diamonds. While a large diamond is rare, a really large one is extremely rare. Also, most diamonds mined in the world will not be of a quality to become gems, and may be used for industrial purposes. Thus, there aren’t many gem quality diamonds

One Carat

One carat is a good sized diamond, makes an impressive statement, and is larger than most people will ever own.

1.00ct Lot 113, Spring 2017

1.00 carat, Lot 113, offered in the Spring 2017 Important Jewels Auction, sold for $4,400.

Two Carats

Two carats, that much rarer than one carat, has a value that is about twice the value, per carat, of an equivalent one carat gem, all other things being equal. Meaning that a two carat diamond is at least twice as rare as one carat, and a two carat diamond will be four times the price of an equivalent one carat (twice the price per carat, plus twice the carats).

Lot 330 Spring 2017

2.14 carat, lot 330, offered in the Spring 2017 Important Jewels Auction, sold for $16,000

As each new carat weight is reached, there can be an increase in price per carat.

Three Carats

Lot 328 Spring 2017

3.00 carat, Lot 328, offered in the Spring 2017 Important Jewels Auction

Looking at the diamonds as they increase in size, the diamond becomes rarer and rarer.

Four Carats

Lot 353, Spring 2017

4.15 carat, Lot 353, offered in the Spring 2017 Important Jewels Auction, sold for $12,000

Most people will never even see a 5 carat diamond, let alone OWN one!

Five Carats

Lot 352, Spring 2017

5.01 carat cushion shaped, Lot 352, offered in the Spring 2017 Important Jewels Auction

There is no question of the obviously impressive visual impact of larger diamonds

Six Carats

Lot 397, Spring 2017

6.35 carat, Lot 397, offered in the Spring 2017 Important Jewels Auction, sold for $90,000

Seven Carats

Lot 334, Spring 2017

7.64 carat, Lot 334, offered in the Spring 2017 Important Jewels Auction, sold for $55,000

Once we get to ten carats, it it enough to make people stop in their tracks. The price per carat really jumps, because ten carats is so rare.

In the Spring 2017 Important Jewels auction, there are six diamonds with a weight greater than 10 carats.

Ten Carats

Antique Jewels: 19th Century

ANTIQUE JEWELS:

VICTORIAN

404

Late Victorian Natural Pearl and Diamond Pendant/Brooch, Lot 404 in the Dupuis Fall 2016 Important jewels Auction

Antique jewels have a story. Sometimes we aren’t told what the story is. We can, however, discover the tale by reading the secrets of the jewel.

History is a moment in time. In antique jewels, these moments are revealed by examining gems, design styles, themes, and metals. Also, owners can help by providing anecdotes, reminiscences, pictures, or documents.

The years from 1800 to 1899 are an important period in history. Pivotally, the industrial revolution changes the way people live, work, travel, and build the things of daily life.

Antique Victorian Hardstone Cameo and 14K Gold Brooch, Lot 512 in the Dupuis Fall 2016 Important Jewels Auction

There is a growing middle class. People are upwardly mobile, with spare spending money. Concentrations of population and wealth in cities creates a growing artist class. Hence there are more decorative items produced and more people using them.

QUEEN VICTORIA

Lot 324 Spring 2017

Victorian brooch by Carlo Giuliano, offered in Dupuis Spring 2017 Important Jewels Auction, Lot 324

Britain’s Queen Victoria is the ruler of the British Empire. At the time, the British rule over a huge part of the world. Victoria reigned from 1837 to 1901. We often call this the Victorian period. Her children marry into many other European royal families. World change in her time is huge.

PHOTOGRAPHY

Victoria is one of the first world leaders to be photographed. It’s the origin of the paparazzi. Every time Queen Victoria goes out, the cameras are also out. Cameras are large and unwieldy in their early days, but photography brings big change. Thus, we all see photos of Victoria and her jewels.

Once upon a time, antique jewels were the latest thing. Now antique jewels are unique wearable works of art. It’s rare to find two identical Victorian jewels. We’re all fascinated by these beautiful and unique works of art.

Lot 97, spring 2017 www.dupuis.ca

Victorian pocket watch, offered in the Dupuis Spring 2017 Important Jewels Auction, Lot 97

In the Victorian Age, our time is more effectively used. More people carry a watch, there are more people with more leisure time. We see more and more information about the world outside of our borders. These borders are both geographic and historic.

Historically, we look at ourselves in our own back yards. The Victorian middle class saw pictures of interesting far-away places. Archaeologists all over Europe, Egypt, and further afield bring ancient art of great beauty to light.

Collectors become obsessed with these artifacts. Therefore, artists begin to explore work of the ancient world. The result is remarkable jewels of jewellers such as Castellani and Giuliano.

The archaeological revival work of these jewellers creates a buzz at auction. These antique jewels are exceptional, inspired by the most beautiful and enduring art of the ancient world.
